JavaScript is a programming language used for building dynamic server-side and client-side websites. Are you a JavaScript developer? Do you want to master JavaScript? Do you want to know how learning JavaScript can help you become a better React.JS, Nest.JS, and Next.JS developer? Read on to find out. 

In a recent interview, Sharafat Ahmed, a software engineer at Turing, answered the most popular questions related to JavaScript., Nest.JS, React.JS, and Next. JS.

Here are the top insights from the interview. 

What is JavaScript?

JavaScript is a text-based programming language used for developing client-side and server-side applications. JavaScript is one of the essentials of web technology, along with HTML and CSS. HTML provides the web page’s structure and content, whereas CSS offers different styling options for the website. Every webpage includes a document object model (DOM) that represents the page’s content in an organized form using HTML. 

JavaScript is used for creating mobile and web applications, building web servers, and developing server applications and games, among others. JavaScript can easily access and manipulate the DOM of every webpage. Thus, JavaScript turns static web pages into interactive pages by modifying HTML and CSS elements, validating data, adding multimedia, inserting dropdowns and menu options, etc. 

What is the learning curve for JavaScript?

JavaScript is one of the easiest programming languages to learn. Developers familiar with HTML and CSS can learn JavaScript with ease. Also, developers can learn how to code and other basic JavaScript operations in a few months. Developers must ensure to write and test the code thoroughly since mastering JavaScript requires following a well-defined code structure.  

What are your thoughts about the statement that JavaScript has changed the web development scenario altogether?

Invented in 1995 after programming languages like Java, C, and C++, JavaScript did not become popular right away. After Netscape added support for JavaScript in 1996, Internet Explorer and Firefox also added support for the programming language in 1997 and 2000, respectively. 

Soon every major browser offered support for JavaScript. And thus, JavaScript became the de-facto programming language for web development. Sure, developers can choose different languages for back-end development, but JavaScript is the go-to choice for front-end development. 

How can learning JavaScript benefit developers?

The software industry is an ever-changing landscape. However, old languages like Java and PHP are still in demand despite people assuming that such technologies will become extinct. Also, in the past 10 years since the launch of React.JS, the JavaScript library has been the most popular.

Learning JavaScript allows developers to utilize all the above-mentioned technologies seamlessly in different projects. Also, the software industry can see the emergence of new skills in the near future. This can benefit the developers well versed in JavaScript as the programming language is one of the mainstays of web technology. Also, with the release of Node.js in 2009, developers started using JavaScript for backend development.

How can JavaScript developers stay relevant in the fast-changing software industry?

JavaScript developers can stay relevant in the fast-changing software industry by learning new things. Since JavaScript is a versatile language, developers must work on different projects. 

Developers working on the front end must try back-end development to enhance their skill set. Similarly, developers working on the back end should take up DevOps or other projects that expand the knowledge and utilization of JavaScript.
